Safe, Low-Pressure Soft Washing for Roofs and Gutters on the Central Coast
Roof and gutter soft washing on the Central Coast is the safest and most effective way to remove dirt, lichen, and algae without damaging your home’s exterior. Traditional high-pressure roof cleaning can lift tiles, strip coatings, or push water into unwanted areas leading to leaks and premature wear.
At Glason High Pressure Cleaning, we use a low-pressure soft washing method designed specifically for roofs, gutters and eaves. Our process dissolves built-up grime and kills organic growth at the source, restoring your roof’s appearance and helping rainwater systems flow freely. Whether your roof is tiled, Colorbond or metal, we’ll clean it thoroughly and safely, protecting both your home and its structure.
We proudly service the Central Coast, including Terrigal, Avoca Beach, Wamberal, Umina, Woy Woy, Erina and Gosford.

Why Roofs and Gutters Need Gentle Cleaning
Your roof and gutters are constantly exposed to moisture, salt and airborne contaminants, the perfect environment for mould, lichen and moss to grow. Over time, this build-up not only looks unsightly but can trap water, weaken seals, and cause premature corrosion or leaks.
Why soft washing is ideal for roofs and gutters:
- Removes lichen, moss and mould without damaging coatings
- Prevents blocked gutters and water overflow
- Safe for painted, tiled and Colorbond surfaces
- Helps prevent leaks and roof deterioration
- Extends the life and appearance of your roof
Soft washing cleans at a chemical level, using detergents and biocide mould killers to kill growths rather than blasting them off, ensuring a deeper and longer-lasting clean.
Our Render Cleaning Process
We tailor our process to suit your roof type and condition, ensuring maximum results with zero risk.

1.
Inspection & Preparation – We assess your roof type and note any problem areas like heavy moss, rust, or blocked gutters.
2.
Pre-Treatment – A biodegradable cleaning solution is applied to break down organic matter and stains.
3.
Low-Pressure Wash – We gently rinse the surface, removing loosened debris without affecting tiles or coatings.
4.
Gutter Flushing – Gutters and downpipes are flushed to ensure proper drainage and remove any built-up sediment.
5.
Final Treatment (Optional) – A protective biocide application prevents future regrowth and keeps your roof cleaner for longer.
Soft Washing vs High-Pressure Roof Cleaning
High-pressure cleaning may look fast and effective, but it can easily dislodge tiles, strip paint, and force water beneath roof sheets or flashing, leading to leaks and long-term structural damage. The intense force can also remove protective coatings from Colorbond and metal roofs, making them more susceptible to rust and corrosion over time.
Soft washing, by contrast, works through chemical action rather than force. Our specialised low-pressure system applies a biodegradable solution that kills mould, algae and lichen at their roots before a gentle rinse washes everything away. This process not only cleans more thoroughly but also prevents regrowth, keeping your roof looking cleaner for longer.
By maintaining your roof’s coatings and seals, soft washing extends its lifespan and helps preserve your home’s energy efficiency, especially for lighter-coloured or reflective roofs that perform best when free from grime and organic build-up.

Common Roof Issues We Treat
The Central Coast’s humid, coastal environment often leads to organic growth, corrosion and water damage, especially on roofs that haven’t been professionally cleaned in several years. Moisture and salt in the air create ideal conditions for moss, lichen and mildew to thrive, while fine dust and pollution from nearby roads and sea spray gradually dull your roof’s appearance.
Left untreated, these issues can cause water pooling, surface deterioration and blocked gutters that affect your home’s overall drainage. Regular soft washing not only restores your roof’s appearance but also helps prevent costly repairs down the track.
We commonly treat:
- Lichen and moss on roof tiles
- Black mould and mildew streaks
- Rust or salt stains on Colorbond and metal roofs
- Clogged gutters and downpipes
- Dirt, dust and pollution build-up
Our soft washing system removes these contaminants safely, leaving your roof clean, healthy and protected from further damage.
